Polymers: Precipitation and Dewatering - Tramfloc, Inc.
As a final note about sludge dewatering, biological sludges such as activated sludge from a waste treatment plant or sludge resulting from an anaerobic biological treatment system are notoriously difficult to dewater. In these cases, inorganics such as ferric chloride or lime are used to assist in the dewatering process.

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin.
